Animated Movie Clip Button Works, but doesn't Loop...

1. I have my movie clip button, "mcAboutus" then inside my movie clip I have 5 layers: actions, labels, text, animated rollover("mcAboutusover"), animated rolloff("mcAboutusoff"). On the labels layer I have _up, _over, _off. On the _up is the text layer, on the _over is a movie clip of the animated rollover("mcAboutusover") which is 90 frames, and I want to loop as long as the mouse is over the text. And the _off has the "mcAboutusoff" movie clip.

So I was able to have the rollover work, but when I roll off the rollover animation continues on until the end of the animation. I understand it has to do with the fact that it's a movie clip, but how do I point it to go into the movie clip and read the animation and that on the last frame of the animation I have a "gotoAndPlay(1);" to have the animation continue looping as long as it's in a rollover state?
here is the code I have for the _root:
